There are two possible solutions for this problem: a client-side and
a server-side one.

client-side:
In /etc/network/interfaces, add a post-up line, for example

iface eth0 inet dhcp
	post-up ifconfig eth0 XX.XX.XX.XX

What it does, after dhclient gets all the info and sets the
interface up, it changes the IP adress to XX.XX.XX.XX.

server-side:
Add following lines to your /etc/dhcp(3)/dhcpd.conf:

# Declaration of the subnet
subnet 10.0.0.0 netmask 255.0.0.0 {

host mybox {
        hardware ethernet XX:XX:XX:XX:XX:XX;
        fixed-address YYY.YYY.YYY.YYY;
}
}

This only works if you have ISC dhcp server running. X is your mac
address and Y is your "static" IP.

The server-side solution is IMHO better because the client-side one
will overwrite you IP everytime it updates its lease. If your lease
time is too short, it may be more of a pita than any help.
